length is 42 m, find its breadth
of its​

Answer 1

Answer:

Let the breadth be = x

$\color{black}\boxed{\colorbox{saffron}{Area - length×breadth}}$

${126}^{2} = {42}^{2} \times {x}^{2} \\ \\ = 15876 = 1764 \times x \\ \\ x = \frac{15876}{1764} \\ \\ x = 9 \\ \\ {x}^{2} = 3 \times 3 \\ \\ x = 3$

So, breadth= 3m

Answer 2

Step-by-step explanation:

Area of rectangular p lot

$l \times b$

42b. =126

b= 126/42

b== 3 m
